How does Eureka Water Association compare with other water systems in Eureka County?
By EPA's size categories, Eureka Water Association is a very small system (500 people or fewer). Eureka County has 13 active public water systems, and Eureka Water Association is the 4th-largest of them by population served. Its population served is about 36% above the county average of 330 people per system, and accounts for 10% of the 4,294 people reported by systems filed under the county. Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active community water system reports serving 6,703 people, so Eureka Water Association is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Nevada has 224 active community water systems, 35% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
Who owns and regulates Eureka Water Association?
EPA lists Eureka Water Association as owned by a local government. The NV state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 4 of the 13 active systems in Eureka County (31%) are also owned by a local government.
Does Eureka Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in October 2024. The violations listed here began between January 2000 and October 2024. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (8 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
